IMPROVEMENT lN APPARATUS FOR DYEING WOVEN OR POROUS FABRICS.

Specification forming part of Letters Patent No. 178,921, dated June 20, 1876; application filed February 28, 1876. v

To all whom it may concern:

Be it known that I, GEORGE OANTRELL GIBBS, of Brentford, in the county ofMiddlesex, England, have invented Improvements in Apparatus for Dyeing Woven or Porous Fabrics; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this specification, in which- Figure l is an end elevation of the appa- Fig. 2 is a side ole vation, partly in section. Fig. 3 is a plan of the lower dies upon a larger scale.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to no el arrangements of apparatus for dyeing in one or more colors, or for printing designs upon felt or other fibrous or porous fabrics.

In the annexed drawing, a to represent the frame-work of the apparatus, carrying the bearings 12 b, in which the driving-shaft a revolves. The shaft 0 is driven by toothed wheels at, or by belts or other convenient means. 0,

' Fig. 2, is a roller, round which the felt or other fabric f is rolled, and fromwhich it is drawn forward at intervals between the dies or pressblocks 9 g by means of the feeding-rollers It h. The lower die g is supported by the frame 1', which is fixed to the frame-work of the apparatus, and the upper surface of the die, which is made preferably of brass, has formed upon it the pattern or design which is to be dyed upon the felt, theparts representing the different colors being separated from each other by the raised part of the die. Anupper die, g,'is a precise counterpart of the lower die, 9, but is made capable of rising and falling vertically in the guides 70 It. -When the felt or other fabric has been passed into its proper position between the dies the upper one, 9, isbrought forcibly down upon it by means of the cam land connecting-rod m, and liquid'dye is forced by means of the pumps 0?. n into the sunken parts of the lower die 9 through the pipes o 0,- and thence through the substance of the felt or other fabric into the upper die 9, from which the air escapes through holes left for that purpose, and round which cisterns may be arranged to receive the surplus dye. The pumps 1 n are driven by cranks and connecting-rods, or by eccentrics or cams, from the driving-shaft c, and when the stroke of the pumps is reversed the liquid die is drawn back through the fabric into the 1 pumps, and is followed by a current of air, by-

which the fabric is dried or partially dried.

The upper die is then released from pressure, and is. raised by the balance-weight p, and the fabric is fed forward. to a sufficient distance by means of the feed-rollers h h, which are actuated by toothed wheels, and an adjustable eccentric or cam, as' shown at r in Fig. 2.

In the drawing dyes of two colors are shown, being used as illustrated in Fig. 3, in which two similar dies or blocks are shown arranged side by side in a frame adjusted by screws. The horizontal line represents dye of one color, which is forced into the dies through the pipes 0 0, and the diagonal lines the dye of the oth- 'instead of by a cam and balance-weight,

or spring arranged in the connecting-rod,

in order to keep the die in contact with the fabric for a suflicient time; and instead of feeding -.rollers, as shown in the drawing, joinetd levers or forks may be used for feeding the fabric forward at theproper time.

Where the coloring-matter is held in suspension in the dye, so that it becomes less strong as the dye passes backward and forward through the fabric, it is advisable to arrange the pumps so that a separate quantity of dye is forced through the fabric at each stroke. In this case the upper part of the pump is closed, and when the piston is near the bottom of its stroke the dye is admitted above it through a valve which is opened by a cam upon the driving-shaft, and is closed when a sufficient quantity of dye has been admitted. f The piston continues its upstroke, and forces the dye through the fabric by a tinuously.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The lower dies 9 and the upper movable perfora ed dies g in combination with the pumps 'n; 'n, and the pipes 0 0, substantially as and for the purposes described. a

2. The combination, with the diesgg" and the pumps and pipes at n 0 0, of the feedingrollers h h and driving-gear 'r, all actuated from the driving-shaft a, substantially, as and for the purposes explained.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.-
